Zoneminder being killed by the oom killer
Posted: Wed Oct 27, 2021 2:25 pm
I recently setup a zoneminder system and it worked ok for a few days and now memory seems to spike on 2 of the zmc processes and the oom killer takes it all down.
I have 2 IP cameras and 2 monitors per camera - a lowres 640x360 and a highres 4K
All 4 stream are rtsp/tcp. All 4 streams are camera passthrough
The lowres monitors are set to Mocord and the highres are set to Nodect. Each of the highres monitors have both of the lowres monitors linked.
Have I created a circular link?
I did increase the limits in systemd for zoneminder from 64K up to 8Mb for max locked memory (LimitMEMLOCK=8192000)
This is what the the monitors look like in top after a new start.
If I trigger an event by walking infront of the camera the 4k monitors spike in ram
And if I trigger it again - it leaks more memory
